Drainage Network Patterns Determinism: A Comparison in Arid, Semi-Arid and Semi-Humid Area of Morocco Using Multifactorial Approach

Simulation of the catchments hydrological processes in arid, semi-arid and semi-humid areas

Hydrological processes and their spatial distribution directly are relevant to climate, topography, geology, and land use in the watershed. Therefore, use of a model whit integrity and high performance for simulating the process in deferent watersheds is very important. In this study was assessment performance of semi-distributed SWAT model in simulating hydrology processes in three watersheds ...

Groundwater level fluctuation forecasting Using Artificial Neural Network in Arid and Semi-Arid Environment

In arid and semi-arid environments, groundwater plays a significant role in the ecosystem. In the last decades, groundwater levels have decreased due to the increasing demand for water, weak irrigation management and soil damage. For the effective management of groundwater, it is important to model and predict fluctuations in groundwater levels. In this study, groundwater table in Kashan plain ...

Drainage Experiences in Arid and Semi-arid Regions Expériences De Drainage Dans Régions Arides Et Semi-arides Des

The state of development of drainage in arid and semi-arid countries is lagging far behind the development of irrigation. This leaves the worlds’ irrigated agriculture at high risk of losing productive lands to waterlogging and salinization. As development of new irrigation projects will not likely happen any more as in the sixties and seventies, drainage of existing irrigated lands can contrib...

Soils of Arid and Semi-arid Areas

00554 - 9 - Arid and Semi - Arid Geomorphology

The world’s arid lands are some of the most beautiful landscapes on Earth, and their paucity of vegetation often makes it possible to see landforms and structures with great clarity (Figure 1.1). In addition, they have many characteristics both in terms of landforms and geomorphological processes that render them different from other major environments (see, for example, Laity, 2008; Parsons an...
