Estimating water balance components of tropical wetland lakes in the Pantanal dry season, Brazil

Abstract: Water balance studies with stable water isotopes have rarely been conducted in remote and tropical wetland areas. As such, little is known regarding the water balance and groundwater-surface water interaction in the Pantanal, one of the largest and most pristine wetlands in the world. We applied MINA TrêS, a water balance model utilizing stable water isotopes (δ 18 O, δ 2 H) and chloride (Cl -) to assess the dry-season hydrological processes controlling groundwater-surface water interactions and the water bala… Show more

“…We can deduce from our study that AET of studied wetland lakes in the floodplain was different among the lakes, which corresponds with the findings of previous water balance studies in the same area (Schwerdtfeger et al, 2013). To study the reasons for the different inundation dynamics was beyond the scope of this study.…”

“…One explanation may be the differences in the micro-topography together with soil types that either impede or accelerate infiltration, and therefore the drying process at a specific location (Bruland et al, 2006). Furthermore, local and regional groundwater fluxes, already observed in the study area (Schwerdtfeger et al, 2013), could also be the reason for discontinuous water level declines or mixing of water level signals induced by lateral connectivity between the water bodies (Tamea et al, 2010). Our results confirm that even during the dry season the evaporation process is still very important (Mesquita et al, 2009).…”

“…Curah hujan merupakan satu-satunya komponen input sedangkan evapotranspirasi, limpasan dan air masuk dalam tanah berada di sisi output (Sebhat, 2014;Ufoegbune et al, 2011). Sementara hasil pengamatan lapangan bisa memberi pertimbangan (adjust) dalam menghitung neraca air (Schwerdtfeger et al, 2014). Perhitungan neraca air dipengaruhi oleh jumlah curah hujan yang jatuh di permukaan bumi dan berapa banyak air yang kembali menguap maupun masuk ke dalam tanah yang dapat diasumsikan dengan persamaan (Suyono dan Takeda, 1987):…”

“…Dengan ditetapkannya wilayah Serang Barat dan Kota Cilegon sebagai kawasan industri, peran Rawa Danau yang merupakan bagian dari DAS Cidanau semakin dibutuhkan sebagai penyedia air. Dalam kondisi normal, semua danau menunjukkan pola kualitatif yang sama dari proses hidrologi dan mampu mengendalikan keseimbangan air (Schwerdtfeger et al, 2014).…”
