The Present Study investigates the relationship between precipitation and
agriculture on the northern littoral plain of Sinai the study is divided into
five chapters preceded by an introduction and followed by aconclusion .
Chapter one; Examines the geographic characteristics and spatial outlines
of North Sinai , along with their impact on agriculture . these are the
surface geological formations, the geological composition , sand dunes, the
system of valleys and dams, distribution of the arable are and urban centers
and catchments of precipitation water.
Chapter Two; tomatoes [ Winter vegetable crop ] : discusses the
meteorological factors influencing rain , including the astronomical and
geographical location , height . forms and directions of the shore ,
distribution of air masses atmospheric fronts and depressions , distribution
of annual , seasonal and monthly rates of climatological elements in North
Sinai , as represented by the distribution of the rater of temperature,winds,
relative humidity and evaporation .
Chapter three; is interested in studying the characteristics and
effectiveness of rain , as represented by examining the monthy properties
of rain, seasonality of rain , peak months of rain , con cent- ration of rain ,
rainy days , probability of rainy days , degree of depending on rain ,
frequency of rain patterns , prospective predictions and change directions
of rain amounts the chapter also handles the effectiveness of rain by
adopting the equations of Lang, Du martone , lois Ambrigie , and Jocobel
on the area under study Evapotramspiration power is also studied adopting
Evamov and penman equauions.
Chapter four; handles rain and crop compounds in North Sinai . it
investigates types of using rain water in agriculture in North Sinai , both
surface and underground water . it also examines the types of agriculture
based on rain and methods of irrigation , along with the types of soil in
North Sinai and crop compound of rain forming . The relationship between
the most important climatological factors and the yield of some selected
crops , such as peach [ horticultural ] barley [ field crop ] , tomatoes
[ Winter vegtable crop ] , melon tomatoes [ summer vegtable crop ] has
been studied along with the relationship between rain and the crop selected.
Chapter five; investigation rain and agrarian problems . They are divided
into natural problems , such as drought, salinity of soil , marching sand
dumes and chemical pollution , and human- based problems , such as
problems of agricultural operations , problems of irrigation water and
problems of the soil. Al-salam canal and its impact on the future of rain
forming has been studied .
