Drainage models: An evaluation of their applicability for the design of drainage systems in arid regions

نویسندگان

چکیده

Only 5%–10% of irrigated lands in least developed countries (LDCs) are currently drained. Although drainage simulation models (DSMs) used to evaluate alternative designs, it is unclear which model suitable for LDCs' arid and semi-arid regions. This study evaluates selected DSMs (ADAPT, RZWQM2, DRAINMOD, EPIC, HYDRUS-1D, WaSim SWAP) critically assesses their applicability areas. Also, establish apply selection criteria based on the availability data LDCs with Libya as a case study, identify most application Libya. DRAINMOD had highest overall score, methods predict missing input parameters discussed. Evaluating feasibility using predicted design systems would help farmers, planners decision-makers reduce cost system and, also, make more accessible tool different designs.

Ecohydrological Control of Deep Drainage in Arid and Semiarid Regions

The amount and spatial distribution of deep drainage (downward movement of water across the bottom of the root zone) and groundwater recharge affect the quantity and quality of increasingly limited groundwater in arid and semiarid regions. We synthesize research from the fields of ecology and hydrology to address the issue of deep drainage in arid and semiarid regions. We start with a recently ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Developing a Drain for Drainage of Seroma: Evaluation of Its Efficacy with External Drainage

Introduction:  Seroma formation continues to be a problem for patients undergoing surgery of the breast or axilla for invasive breast cancer. In general, seroma usually disappears within several weeks; however, some patients are troubled by chronic seroma. Several techniques have been utilized to minimize seroma formation, with no consistent success. Considering the high prevalence of seroma in...

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...
