Saya mau tau Sajarah hidrologi dari Hidrologi. Jelaskan dalam bahasa sunda

Hidrologi jadi salah sahiji subyek panalungtingkan jeung rekayasa keur sababaraha milenia. Contona, dina kira-kira 4000 S.M. walungan Nil dibendung keur naekkeun hasil tatanen di wewengkon nu tadina tandus. Kota Mesopotamia ditangtayungan tina banjir ku tembok taneuh di jangkung. Saluran cai diwangun ku Yunani Kuno jeung Romawi Kuno, sedengkeun Sajarah China ngawangun irigasi jeung wangunan keur ngontrol banjir. Sinhale Kuno ngagunakeun hidrologi keur ngawangun Kompleks Irigasi di Sri Lanka Kuno, dikenal salaku nu manggihkeun Lobang Klep nu bisa dipaké keur nyieun tempat panampungan cai nu gedé, saluran cai nu nepi ka kiwari masih kénéh dipake.

Marcus Vitruvius, di mimiti abad S.M., ngagambarkeun téori filosofis siklus hidrologi, hujan anu murag di gunung nyerep ka jero taneuh sarta nuju ka walungan sarta usum semi di wewengkon lengkob. Kalawan nyoko pendekatan anu leuwih ilmiah, Léonardo da Vinci sarta Bernard Palissy sacara teuneung mere gambaran nu pas siklus hidrologi. Henteu nepi ka abad ka-17, yén variabel hidrologi mimiti diukur.

Pelopor élmu pangaweruh hidrologi modérn nyaéta Pierre Perrault, Edme Mariotte jeung Edmund Halley. Kalawan ngukur curah hujan, runoff, sarta lega drainase, Perrault méré conto yén curah hujan éta téh mahi keur ngajelaskeun aliran ka walungan Seine. Marriotte ngahijikeun kecepatan sarta penampang melintang sungai keur ngitung debit walungan Seine. Halley némbongkeun yén penguapan ti Laut Mediterania nyaéta mahi keur ngajelaskeun ngocorna cai walungan ka laut.

Advances in the 18th century included the Bernoulli piezometer and Bernoulli's equation, by Daniel Bernoulli, the Pitot tube. The 19th century saw development in groundwater hydrology, including Darcy's law, the Dupuit-Thiem well formula, and Hagen-Poiseuille's capillary flow equation.

Rational analyses began to replace empiricism in the 20th century, while governmental agencies began their own hydrological reséarch programs. Of particular importance were Leroy Sherman's unit hydrograph, the infiltration théory of Robert E. Horton, and C.V. Theis's Aquifer test/equation describing well hydraulics.

Since the 1950's, hydrology has been approached with a more théoretical basis than in the past, facilitated by advances in the physical understanding of hydrological processes and by the advent of computers and especially Geographic Information Systems (GIS).
