These standard faults form en echelon fault blocks which make, in a few places, isolated avenues of ground-h2o movement and ground-h2o obstacles. Similar fault Charge of ground-drinking water move can be noticed in Holt's (1956) potentiometric area map of Medina County, which can be also situated in the Balcones fault zone. He demonstrated that faults with major displacement develop boundaries to ground-drinking water movement Which water will "spill out" into an adjacent fault block wherever the displacement from the faults decreases.
It includes broad valleys and large stream divides with fairly couple of steep, high-gradient canyons. The Lampasas and San Gabriel Rivers are the only real two big streams that bisect the realm.

The consequences of storm activities on spring-drinking water chemistry are shown at Comal Springs by plots of chosen chemical and Actual physical parameters as opposed to time for your couple of October rains (Figure 18 and Figure 19). All spring orifices reacted likewise. Modest rains transpiring on Oct 6th and 8th, 1982, did not considerably change the spring-water chemistry, but an inch of rainfall on October 10th did. This larger rainfall enhanced the temperature and brought in soil nitrates. Fecal coliform germs and phosphate amounts did not alter. Calcium hardness elevated but magnesium, sulfate, and chloride amounts lowered. These knowledge surely display that some new, community recharge waters are achieving the springs. That is Opposite to prior considered, determined by lower tritium values (Pearson et al., 1975). A tritium worth of 5.0 + 0.5 T.U. was produced for Comal 1 on the sample collected in October, 1984, throughout a serious drought. It is possible that throughout bigger storms, a ground-drinking water "wedge" of the latest water may possibly sort close to the Comal Springs orifices.
The potentiometric surface map also implies that ground h2o is going from the San Antonio portion of the aquifer confined in between the San Marcos Springs fault and Comal Springs fault. Each and every of those faults has about three hundred feet (90 m) of displacement, and each are thought to kind hydrologic limitations to ground-drinking water motion.
