ABSTRACT Flash floods frequently occur in Indonesia. Flash flood can be caused by natural and human factors. This paper discusses the causes and mitigation of flash flood using a case study in Banyuwangi. On June 22th 2018, flash floods occurred in the residential areas of Garit, Karang Asem, and Bangunrejo Hamlets. Flash floods were triggered by heavy rainfall the day before, which reached 90 mm/day. The three hamlets are located in Alasmalang Village, Singojuruh Subdistrict, Banyuwangi District. The study began with a field survey, analysis of the damage, and the causes of a flash flood, and its alternative treatments. The suspected source of the material was the landslide material, approximately two million cubic meters from the Pendil Mountain. Some of the material were carried away by the river flooding caused flash floods in the three hamlets. The small width of the bridge was not able to be passed by trees and other flash flood material, so water overflowed the roads and houses. Based on the results of the study, it is recommended for disaster mitigation in the form of structural and non-structural actions. Structural measure in the form of bridge elevation and construction of sediment retaining weirs, while non-structural actions are in the form of an early warning system and dissemination of flash flood hazards.

Population growth, urbanization, industrial development, and agricultural activities increase water demand on the watershed. An increase in water demand will propagate the excessive exploitation of surface water and groundwater resources. This will probably influence the water balance of the watershed. Therefore, understanding the water balance is a necessity. Continuous imbalance between water supply and demand will generate many serious environmental problems. A study of agricultural water balance is needed to answer the question whether the available water resources can meet the needs of sufficient water for irrigation. The study was conducted in Rawatamtu sub-watershed which was part of Bedadung Watershed. The Water Evaluation and Planning (WEAP) model was used to analyze agricultural water balance. The procedure included inventory data, installing WEAP on the system, running the WEAP, and using WEAP for simulating future water balance conditions. The simulation results showed that agricultural water balance for the next 10 years will be more frequently in surplus condition rather than in deficit condition. The water surplus was estimated to occur in the year of 2020, 2021, 2023, 2025, 2027 and 2028. The highest surplus occurred in the year of 2028 which reached 56.59 million m3. Furthermore, the potential water balance deficit was projected to occur in 2019, 2022, 2024 and 2026.

Most bamboo has a tight sympodial rhizome root system that can be used for conservation of river border. Generally, bamboo in each watershed has a variation, such as in Tiupupus watershed North Lombok District, there were found 4 bamboo genera, 9 species, and 1 variety while in Meniting watershed, West Lombok District, there were found 6 genera of 8 species of bamboo. This study aims to determine species of bamboo and its distribution along buffer zones of the Kedome river in East Lombok District. Sampling method was conducted by exploring the bamboo in the buffer zone as long as 6.000 m, the width of the two paths on both sides of the river was 50 m each. Data were analyzed using description method. The results showed: there were 3 bamboo genera, 5 species and 1 variety e.g. Gigantochloa apus, Gigantochloa atter, Thyrsostachis siamensis, Bambusa maculata, Bambusa vulgaris, and Bambusa vulgaris var. vittata. Species of Gigantochloa atter and Bambusa vulgaris have tight sympodial rhizome roots, rounded and thick canopy. Both types of bamboo are recommended to be used as soil and water conservation plants in the watershed.

Flood is one of natural disasters that often occur in Indonesia. This disaster also occurred in Bima City on December 21, 2016, December 23, 2016, and January 2, 2017 with the affected area were Mpunda, Rasanae Timur, Asakota, Rasanae Barat, and Raba districts. The urban areas become the most affected areas, mainly in the residential areas that located more than 50 meters from the flood plains. The variations of flood heights ranged from 1-4 meters. In addition to the hydrometeorological factors, the flood in Bima was caused by several factors, such as: loss of riparian areas function which turned into settlements nowadays, siltation in the downstream areas, poor management of urban drainage systems, reduced vegetation cover in upstream, and narrowing of river bodies. With the increasing of hydro-meteorological disaster problems and challenges, recommendations of structural and non-structural infrastructure to reduce the risk of flood disaster are needed. Therefore, this research aims to provide recommendations of structural and non-structural as an effort to mitigate flood disaster in Bima City. Analytical methods used in this research were participatory mapping, flood hazards mapping and modeling, and qualitative description. Results showed that the management of Rontu watershed in controlling flood would be effective and efficient by combining the structural and non-structural development. Mapping and modeling the flood-affected areas can become a source in the riparian planning regulation to reduce the risk of flooding .

The percentage of forest coverage holds an important role in regulating water in watersheds. This paper studies the influence of forest coverage percentage on peak discharge in sub watersheds with various percentage of natural forest areas. The study took place in Bakar, Tanjung, Iwakan, and Langsat Sub Watersheds, Tanah Laut Regency, South Kalimantan Province in 2017. The percentage of natural forest varied from 9,7 to 98% of the the sub watershed areas. This research was conducted by direct measurement of rainfall and stream water levels that were converted into peak discharge. The p eak discharges between sub watersheds were compared to the rainfall and the percentage of forest. The r esults showed that in general the percentage of natural forest coverage affect the peak discharge. The forest coverage showed a positive response in lowering the peak discharge when the rainfall was below 115 mm/day. Bakar and Tanjung Sub Watersheds that had low percentage of natural forest c overage had higher peak discharge than Langsat and Iwakan Sub Watersheds, which had higher percentage of forest coverage. The relationship between the percentages of natural forest coverage with peak discharge marked by the coefficient of determination value of 5 3 . 3 %. Since the existence of forest is very important as the hydrological controller, forest conservation efforts and reforestation should be conducted in the upper sub watersheds.
森林覆盖率的百分比在调节流域的水方面起着重要作用。本文研究了不同天然林面积比例的子流域森林覆盖率对洪峰流量的影响。该研究于2017年在南加里曼丹省Tanah Laut Regency的Bakar, Tanjung, Iwakan和Langsat子流域进行。小流域的天然林比例从9.7%到98%不等。这项研究是通过直接测量降雨量和转换为峰值流量的河流水位来进行的。将流域间的峰值流量与降雨量和森林覆盖率进行了比较。结果表明，总体而言，天然林覆盖率对洪峰流量有影响。当降雨量低于115 mm/d时，森林覆盖率对降低峰值流量表现出正响应。天然林覆盖率较低的巴卡尔和丹戎流域峰值流量高于森林覆盖率较高的朗沙特和岩坎流域。以决定系数为5 3表示的天然林盖度百分比与峰值流量的关系。3%。由于森林的存在作为水文控制者是非常重要的，因此应在上游小流域进行森林养护和再造林。

Drought identification is needed as a baseline for its mitigation. Several drought identification methods are available, but they need to be tested in dry climates. The purpose of this study was to identify dry area and its mitigation in Moyo Watershed, West Nusa Tenggara Province. Paimin and Syarif methods were used in the study. The results showed that the Paimin method produced a uniform vulnerability map, which was "medium vulnerable" for the entire watershed. This is because the applied parameters only have one class for the entire watershed. The Syarif method provides more variable results because the parameters produce several classes of vulnerabilities. However, the later method has a weakness in applying the depth of groundwater. Moyo watershed only had one class, whereas the depth of the groundwater level varied from 4 to 11 m in the dry season. The two methods produced the same results and there were classified as “medium susceptible” for Moyo watershed. For dry areas, it is necessary to reclassify the drought class of each parameter. By combining the two methods above, it is expected to obtain more accurate results. To get the Water Use Index parameter efficiently, the number of population and water usage should be more efficient. Extentions to the community about the effectively water usage is important. Adaptation to drought can also be done by making reservoirs and setting cropping patterns.
