Abstract :
Mashhad Plain is one of the most important plain in Khorasan_e_Razavi province. In the last decades, rapid population growth coupled with agricultural expansion has tremendously increased pressure on the groundwater resources. Large increases in water demand with little recharge have strained the plain groundwater resources resulting in declines in water levels in last decades. Due to declining of the groundwater level, digging new wells has been forbidden since 1965. As a result of dropping in groundwater levels, land subsidence appears in some parts of the plain. For example, in northeastern part of the plain in Hasan Khordu village area, intensive dropping of the groundwater level has created cracks on the land and buildings. This paper deals with declining of groundwater level and land subsidence in this part of the plain.
