A hydrometeorological study is made of the Septemb.r, 1900 severe rain.torm which led up to the record rain.alls over Gan.etic West b.n.al with sub.equen. disastrous floodin. in.the Damodar an. the Hooghly rivers. The spatial exten. of the rain.torm for differen. duration. has b.en.examin.d b. con.tructin. the isohyetal pattern. b.sed on.rain.all records of station. affected b. the storm. Areal rain.alls for 1,2 an. 3-day periods are calculated an. the values have b.en.compared with similar values from other major rain.torms of the region. The comparison.revealed that the Septemb.r, 1900 rain.torm was the heaviest for 1,2 an. 3-day duration. for all the areas. The storm con.rib.ted rain.alls of 33.0 cm, 52.0 cm an. 62.0 cm over an.area of 10,000 km2 in.1,2 an. 3 days respectively. This rain.torm could, therefore, b. con.idered as an.importan. in.ut in.flood an. design.storm studies in.the Gan.etic West b.n.al region. A relation.hip b.tween.poin. to areal rain.all has also b.en.developed with a view to evaluate areal PMP estimates.

In.this paper, a method to con.truct ob.ique wave-free poten.ials in.the lin.arised theory of water waves for water with un.form fin.te depth is presen.ed in.a systematic man.er. The water has either a free surface or an.ice-cover modelled as a thin.elastic plate. For the case of free surface, the effect of surface ten.ion.may b. n.glected or taken.in.o accoun.. Here, the wave-free poten.ials are sin.ular solution. of the modified Helmholtz equation. havin. sin.ularity at a poin. in.the fluid region.an. they satisfy the con.ition. at the upper surface an. the b.ttom of water region.an. decay rapidly away from the poin. of sin.ularity. These are useful in.ob.ain.n. solution. to ob.ique water wave prob.ems in.olvin. b.dies with circular cross-section. such as lon. horizon.al cylin.ers sub.erged or half-immersed in.water of un.form fmite depth with a free surface or an.ice-cover modelled as a floatin. elastic plate. Fin.lly, the forms of the upper surface related to the wave-free poten.ials con.tructed here are depicted graphically in.a n.mb.r of figures to visualize the wave motion. The results for n.n.ob.ique wave-free poten.ials an. the upper surface wave-free poten.ials are ob.ain.d. The wave-free poten.ials con.tructed here will b. useful in.the mathematical study of water wave prob.ems in.olvin. in.in.tely lon. horizon.al cylin.ers, either half-immersed or completely immersed in.water.

Due to the in.reased deman. for en.rgy resources these days, especially due to the Russian.Ukrain.an.war, the focus of the major coun.ries is turn.n. stron.ly towards improvin. oil production. especially heavy an. extra heavy oil, which represen.s 40% of the world oil reserve. Steam-b.sed an. thermal (EOR) procedures are promisin. techn.ques for recoverin. heavy oil reservoirs, b.t they suffer from a sequen.e of prob.ems an. complication. that arise after lon.-term application. These complication. comprise steam b.eakthrough, steam overlap, an. steam/rock in.eraction.. This research presen.s the curren.ly applied techn.ques to maximize the productivity of heavy oil, such as steam in.ection. cyclic steam stimulation. in.situ comb.stion. an. steam-assisted gravity drain.ge. Thermal techn.logies face n.merous ob.tacles, as they are en.rgy an. water-in.en.ive processes that are n.t en.iron.en.ally frien.ly. The research also presen.s future tren.s in.en.rgy-savin. an. en.iron.en.ally frien.ly techn.ques that en.an.e heavy oil recovery through vapor extraction.(VAPEX) steam-solven. hyb.id techn.ques, electromagn.tic en.rgy, son.cation. an. n.n.techn.logy. The fin.in.s of this review reported that all the presen.ed techn.ques focus on.how to reduce the oil viscosity an. in.situ upgrade the crude oil properties. In.turn. these en.an.e b.th the productivity rate an. oil recovery an. min.mize the production.cost.
