In this study we propose a multi-source data approach for quantifying long-term flooding and aquifer recharge in ungauged ephemeral rivers. The methodology is applied to the Buffels River, at 9000 km2 the largest ephemeral river in Namaqualand (NW South Africa), a region with scarce stream flow records limiting research investigating hydrological response to global change. Daily discharge and a...

the scientific community agrees that climate change is one of the greatest challenges that oursociety will have to face this century. indeed, the fourth report from the intergovernmental panel on climatechange (ippc) confirms the certitude of this phenomenon and its impacts, which can range from droughts tofloods, health problems and food shortages. the principal objective of this paper is to a...

rivers are important water resources for human life, but sometimes cause irreparable damages. the flood plains are fertile terrains which are endangered by flood. flood hazard mapping is one of the basic methods in flood fighting. in order to decline flood damages, the simulation of the hydraulic behavior of the rivers during flood occurrence is very important. in this study, areas that are flo...

Received XXXX; accepted XXXX Abstract Series of observed flood intervals, defined as the time intervals between successive flood peaks over a threshold, were extracted directly from eleven approximately 100-year streamflow datasets from Queensland, Australia. A range of discharge thresholds were analysed that correspond to approximately 3.7 months to 6.3 year return periods. Flood interval hist...

predicting the hydraulic behavior of the river and flood zone determination to reduce probable damages, are among measures which in recent years has been the attention of many researchers. mazandaran province, especially the city of neka, each year is affected by the floods with different return periods; therefore, land use changes and the role of these changes were evaluated in flood zones. in...
