Amount of water in a catchment is major concern for both water supply
and flood management in environmental systems. Water budget analysis gives an opportunity to represent and utilize
hydrometeorological cycle, transport and storage of water in a basin. In this
study, a water budget study that considers precipitation, river runoff,
evapotranspiration, and ground water elevations for an urbanized watershed in
the USA is presented. The urban basin, namely C11, is located in south-central
Broward County, in South Florida in the USA. In this study, all the required
data is obtained from the South Florida Water Management District's (SFWMD)
hydrometerological database (DBHYDRO). Water
budget results show that errors in the storage vary inversely proportional with
increment in the temporal resolution. Annual water budget calculations provide
the most consistent results that is approximately 10 percent of total out/in
flow. Moreover, minor errors proofs that more proper results are captured during
dry season months compared to one in wet
season months

Bir havzada bulunan su miktarı, su temini ve feyezan yönetimi için
çevresel sistemler açısından önem arz eden iki konudur. Bu noktada, su bütçesi
analizi havzalardaki suyun hidrometeorolojik döngüsü, taşınması ve
depolanmasını temsil etme ve kullanmaya olanak sağlar. Bu çalışmada, ABD'nin
Florida eyaletinde bulunan Güney Broward bölgesindeki kentsel bir havza olan
C11 havzası kullanılmış olup, bu havza üzerindeki yağış, akarsu, evapotranspirasyon,
yeraltı suyu verileri dikkate alınarak bir su bütçesi analizi sunulmuştur. Analizde
kullanılan bütün veriler Güney Florida Su yönetimi Bölgesi (SFWMD)
hidrometeorolojik veritabanından (DBHYDRO) elde edilmiştir. Sonuçlar depolama
alanındaki hataların zamansal çözünürlükteki artışla ters orantılı olarak
değiştiğini göstermektedir. Elde edilen veriler, yıllık su bütçesi analiziyle
en tutarlı sonuçların elde edildiğini ve yaklaşık olarak toplam akışın yüzde
10' una karşılık geldiğini göstermektedir. Ayrıca, az yağış alan sezondaki
hataların diğer aylara kıyasla daha uygun olduğu gözlemlenmiştir.
