Submerged notches that indicate negative sea level change evidence during The Quaternary. Through their study, the effects of sea level change and effect of tectonic lifting movements on them during the Quaternary are identified. Submerged notches as negative evidence below MSL are studied in the field work in two areas: The first one is "San Foca" area that comprises three parts from north to south:" Torre di Roca Vecchia bay" and "Madonna di Roca Vecchia bay", the second area is "Castro", only "Porto Castro" is studied below the current sea level. The studied area located in the Ionian Sea coast, South Italy, its total length is about 53 km. The studied area is the south-east part of the Apulia region (southern Italy), stretching between the Ionian Sea and Adriatic Sea. It is located on the east coast of the Salento peninsula. Its coordinates are 40 ̊ 0 ́ 2.43 ̋ to 40 ̊ 18 ́ 6.85 ̋ N, and 18 ̊ 16 ́ 10.10 ̋ to 18 ̊ 31 ́ 30.99 ̋ E The aims of this paper to define the effects of the Quaternary Sea level change on submerged notches, and study the evolution of coastal karst in current climate conditions. The methodology of this study depended upon extensive field and measurements of submerged notches, an in addition to GPS.
表明第四纪期间海平面负变化证据的淹没缺口。通过研究，确定了第四纪海平面变化和构造抬升运动对它们的影响。在两个区域的实地工作中，研究了MSL以下的淹没缺口作为负面证据:第一个区域是“San Foca”区域，由北向南三部分组成:“Torre di Roca Vecchia bay”和“Madonna di Roca Vecchia bay”，第二个区域是“Castro”，仅研究了当前海平面以下的“Porto Castro”。研究区位于意大利南部爱奥尼亚海沿岸，全长约53公里。研究区域是阿普利亚地区(意大利南部)的东南部，延伸到爱奥尼亚海和亚得里亚海之间。它位于萨伦托半岛的东海岸。坐标为40°0°2.43°~ 40°18°6.85°N, 18°16°10.10°~ 18°31°30.99°E。本文旨在明确第四纪海平面变化对淹没槽的影响，研究当前气候条件下海岸岩溶的演化。本研究的方法依赖于广泛的野外和水下凹痕的测量，以及GPS。

The human impact on the environment is of growing preoccupation to be able to understand the formation of the contemporary landscapes and to be able to analyse the various phases of the development of a particular cultural landscape. The impressive mountain landscapes in the Andean region in South America we observe today are not as pristine and untouched, as one could be tempted to believe but it is only recently being recognized as such. The arrival the Spaniards in the 16th century changed the landscape with the introduction of new crops, animals and technology. But the Pre-Hispanic cultures had long before altered the landscape. Changes in subsistence strategies, demography, or perception illustrate complex causes that provide important insights into different utilization systems. Examples are taken from the author’s fieldwork in the Andes and in the Ceja de Montaña.
为了能够理解当代景观的形成，并能够分析特定文化景观发展的各个阶段，人类对环境的影响日益受到关注。我们今天看到的南美洲安第斯地区令人印象深刻的山地景观并不像人们可能会相信的那样原始和未被破坏，但直到最近才被认识到这一点。16世纪西班牙人的到来改变了这里的景观，带来了新的作物、动物和技术。但早在前西班牙文化改变景观之前。生存策略、人口统计或观念的变化说明了复杂的原因，为了解不同的利用系统提供了重要的见解。例子取自作者在安第斯山脉和Ceja de Montaña的实地工作。

This study reviews a number of hydrological modelling studies in arid areas, including the use of spatial analysis in geographical information systems (GIS) and remote sensing (RS) packages. Specifically, it aims to review the most important GIS tools and spatial data used in modeling processes. We discuss the use of digital elevation model data, land-use/cover data, soil data, and rainfall data in terms of their impacts on applications of hydrological modelling. The review concentrates on commonly used tools, e.g., the soil and water assessment tool, the kinematic runoff and erosion model, the identification of unit hydrograph and component flows from rainfall, the evaporation and stream flow model, and the Hydrologic Engineering Center-Hydrologic Modelling System. The runoff curve number method is illustrated as an example of methods that are utilized in GIS-based hydrological models. Arid areas require more attention from researchers in order to overcome the obstacles to hydrological modelling identified in the study. For example, they should consider new methods for determining spatial rainfall and infiltration from transient flows that come from flash floods. Instead of using gauged data on arid areas, RS data can be used for simulating events. Observational data can also be improved by creating multiple measurement stations in affected areas.

Aim: This study aims to monitor the degradation of natural vegetation cover (particularly in juniper trees’ ecosystem) in one of the richest areas of biological diversity in the Kingdom of Saudi Arabia caused by intensive anthropogenic activities. Location: Aseer area located in the southwestern part of Saudi Arabia, it extend between the latitudes of 17° 30ˊ: 21° N and the length of 41° 30ˊ: 44° 45ˊ with total area about 84,084 km2. Methods: Satellite images analysis were used to detect the changes in natural vegetation cover in the study area. These satellite images covering the period between 1980 and 2020. Results: The total area covered with natural vegetation was 4385.6 km2 in 1980; it deceased to 3645.5 km2 according to the satellite image of 2020. Population growth and urban sprawl were the main factors causing the degradation of natural vegetation cover in this region.

Natural reserves are major economic components of countries, due to their natural, human, environmental and tourism importance. Therefore, this study aims to create an interactive map of natural reserves in Egypt, which have 30 existing natural reserves, and 14 suggested natural reserves, On the other hand, today's world is moving to use technology in all directions, including maps. So, this study depends on using Open-Source Web GIS Tools in creating the interactive map, instead of traditional paper maps. Web GIS is the result of merging the advantages of geographic information systems and the possibility of the Internet. This creates maps of easy access and manipulation. Open-Source tools are free to use tools for users to develop on. This study relies on Web design programming languages (HTML CSS – Java Script) for map creating using the Leaflet.js mapping library, and type of data Geojson, and software that uses QGIS for mapping work, and Brackets for coding.
