Climate change impacts on surface water resources in arid and semi-arid regions: a case study in northern Jordan

Climate is an important factor which formed and affected surface water resources. Through sensitivity analysis of natural runoff towards climate change, assuming the main factors effect runoff are precipitation and temperature, then according to the possible tendency of climate changes in the future, set climate scenarios, and use the hydrological model simulate the changes trend of runoff under different climate scenarios, thereby analyze the climate change impacts on surface water resources. The results show that annual runoff will be increased with the increasing annual precipitation, and it will be reduced with rise of annual temperature, the sensitivity that annual runoff towards the change of precipitation and temperature are equally notable, both of them are two major factors impact on the change of runoff and the precipitation change impacts on annual runoff will be even more obvious in flood season. Last, with the global warming trend, put forward the corresponding adaptive measures of energy conservation and emissions reduction。

<p>Countries in North Africa are facing water scarcity and a high inter-annual variability of precipitation. In this context, many dams have been built to collect surface water and improve the management of existing water resources. We present the main results of a recent MISTRALS-ENVIMED research project about the potential climate change impacts on water resources at the regional and basin scales. The project notably focuses on the uncertainties linked to the different components of the modelling chain required to produce hydrological scenarios. Climate change impacts on surface water resources are investigated using an ensemble of regional climate model simulations from the CORDEX experiment under different emission scenarios and different hydrological models, adapted to the context of data scarcity. Climate scenarios under RCP4.5 and RCP8.5 over North Africa indicate a future decrease in precipitation together with an increase in temperature that could have significant impacts on water resources. Indeed, a future decrease of surface water availability is expected in all major dam catchments, with a stronger decline over Morocco.</p>

AbstractSemi-arid regions are known for erratic precipitation patterns with significant effects on the hydrological cycle and water resources availability. High temporal and spatial variation in precipitation causes large variability in runoff over short durations. Due to low soil water storage capacity, base flow is often missing and rivers fall dry for long periods. Because of its climatic characteristics, the semi-arid north-eastern region of Brazil is prone to droughts. To counter these, reservoirs were built to ensure water supply during dry months. This paper describes problems and solutions when calibrating and validating the eco-hydrological model SWIM for semi-arid regions on the example of the Pajeú watershed in north-eastern Brazil. The model was calibrated to river discharge data before the year 1983, with no or little effects of water management, applying a simple and an enhanced approach. Uncertainties result mainly from the meteorological data and observed river discharges. After model calibration water management was included in the simulations. Observed and simulated reservoir volumes and river discharges are compared. The calibrated and validated models were used to simulate the impacts of climate change on hydrological processes and water resources management using data of two representative concentration pathways (RCP) and five earth system models (ESM). The differences in changes in natural and managed mean discharges are negligible (< 5%) under RCP8.5 but notable (> 5%) under RCP2.6 for the ESM ensemble mean. In semi-arid catchments, the enhanced approach should be preferred, because in addition to discharge, a second variable, here evapotranspiration, is considered for model validation.
