Now floodwater spreading on aquifers is one of the suitable methods for control and efficient use flood and artificial feed groundwater in arid and semi-arid regions and determine appropriate locations with accuracy and required speed for floodwater spreading it is of utmost importance. In this study, were identified main criteria four, sub criteria eight and indicators 24 Criteria, sub criteri...

Floodwater spreading for the artificial recharge of groundwater (ARG) is a logical alternative to build large dams for water resources management in dry environments so that it not only enhances water security, but also reclaims the degraded land due to the settlement of suspended load on the spreaders. However, translocation of very fine clay minerals existing in floodwater decreases the infil...

Determine appropriate locations with accuracy and speed required is for Floodwater spreading very important. The main objective of this research, preparation, use and evaluation decision support systems is based on GIS and RS techniques to identify and prioritization appropriate areas Floodwater spreading in the study area. In this study area suitable for flood water spreading were selected bas...

Discharge and water temperature measurements in the Skaftá river and measurements of the lowering of the ice over the subglacial lake at the western Skaftá cauldron, Vatnajökull, Iceland, were made during a rapidly rising glacial outburst flood (jökulhlaup) in September 2006. Outflow from the lake, flood discharge at the glacier terminus and the transient subglacial volume of floodwater during ...

A spatially-explicit, two-dimensional model was developed to evaluate the processes which determine the fate and transport of nitrogen (N) in wetland systems. The wetland soil profile was partitioned into floodwater, and aerobic, and anaerobic soil layers, with diffusion and settling accounting for the transport of N between layers. Nitrogen transformations considered in the model were; enzyme ...

In Malate, a district of Manila, flooding is frequent occurrence. This paper draws on in-depth interviews with Malate inhabitants to approach urban floods as more than discrete disastrous episodes which interfere pre-existing normality. The employs Levebvrian conceptualisation rhythm and entrainment, while also offering reflections the limits its relevance global South cities. Theorised from po...

In arid and semi-arid regions of the world including Iran, floodwaters are the main resource to supply irrigation water. Floodwater spreading also plays an effective role in replenishing groundwater, stabilization of alluvial soil, and vegetation restoration. Qazvin traditional garden is an example of such floodwater spreading mechanism, dating back to over a thousand years ago, according to hi...

Dieback of native Eucalyptus largiflorens forests is an increasing problem on the floodplains of the lower River Murray, southern Australia. Salinisation of floodplain soils, as a result of the changed hydrological management of the River Murray, appears to be a primary cause of the dieback. Regulation of the River Murray has reduced the frequency of large flood events by a factor of approximat...
