This research aims to study the reality of the impact of climate change on water resources in Wadi (valley) of Hadhramout, as this region is exposed to the impacts of climate change on groundwater resources, through the effects on rainfall and surface water supplies. Climate change is a global phenomenon affecting water resources, so it is necessary to study its impact, specifically on the water reserve in wadi of Hadhramout. from this point of view this problem was taken into account in our study in terms of the possibility of maintaining the balance of water reserves in the study area. This paper focused on the problem of climate changes that emerging in wadi of Hadhramout through the scarcity of freshwater. The research aims to identify the realistic causes that led to this problem. During the field visits to the study area, working wells were counted and the difference in the groundwater level was tracked, and monthly and annual rainfall data were collected in the region. Data were collected from water resources monitoring stations. Acquired data were statistically analyzed and presented. The research showed that there has been a noticeable decline in the total amount of rainfall in the last thirty years, specifically from 1981 until 2010 in the study area, which affected the water resources in wadi of Hadhramout area. The results were compared with the calculated total average monthly and annual rainfall for the same period of the study and revealed that there is an effect of climate changes on the water resources stock in wadi of Hadhramout due to the decrease in rainfall and the spacing of its periods, which is the main feeder of the water reserve, in addition to the effect of the observed rise in temperature during the past 30 years.
