In paralel cu cresterea cererii de apa subterana , s-au dezvoltat tehnici si metode de determinare mai precisa a resurselor optime de exploatare,calculul captarilor , monitoringul exploatarii, controlul si combaterea poluarii, astfel incat utilizarea apelor subterane sa se faca in limite rationale , prevenind efectele ecologice nedorite , cele mai importante putand fi epuizarea resurselor si deteriorarea calitatii apei prin poluare.

Titlu: Interactiunea dintre sistemul acvifer si colectorul general de canalizare realizat in cadrul lucrarilor de amenajare a raului Dimbovita in municipiul Bucuresti . Studiu de caz intr-o sectiune reprezentativa
Student: Dan Andrei
Indrumator stiintific: Dr. ing. Radu Constantin Gogu
Perioada: 2010 - 2011
Institutia: Universitatea Tehnica de Constructii Bucuresti - Catedra de Hidraulica si Protectia Mediului
Cuvinte cheie: amenajari hidrotehnice, modelare hidrogeologica , hidraulica si hidrologie urbana, colector general de canalizare

In Bucuresti Dambovita trebuie sa asigure colectarea apelor menajere si din precipitatii precum si tranzitarea viiturilor in conditii de siguranta maxima. Pentru amenajarea Dambovitei s-a adoptat solutia unei cuve de apa curata cu sectiune deschisa si un colector inchis amplasat sub cuva de apa curata, care colecteaza toate apele menajere si pluviale din Bucuresti.
Deoarece acest colector este expus la gaze nocive, ape uzate agresive cu un chimism ridicat, coroziune, dar si datorita neetanseitatii provenite din executie, apar infiltratii. Atat dinspre colector spre sistemul acvifer cat si invers.

Fiecare componenta a mediului are o dinamica proprie ,diferita in timp si spatiu ,cu posibilitati contranstante de autoepurare.Dintre acestea ,solul reprezinta component acumulatoare a mediului .
Solul are insusirea de a inmagazina, pentru perioade foarte lungi  de timp ,de ordinul zecilor sau chiar sutelor  de ani, elemente si substante chimice anorganice  si de a avea un effect degradator mult mai rapid asupra substantelor chimice organice. ( Geo-Atlasul municipiului Bucuresti-2008)

Abstract:

While the physics of mixing and reaction is well understood at the pore scale, the quantification of these processes at the scales relevant for applications is highly challenging. The inability to sample all the subsurface spatial heterogeneity implies that the processes involved need to be averaged. The loss of information induced by this procedure causes anomalous behaviors of the upscaled dispersion and reaction rates. As mathematical and numerical upscaling of such processes is challenging and such upscaling procedures need to be verified to become useful for proper transport prediction, the project here focuses on experimental laboratory scale upscaling of flow and transport. 
In a first study we examined the potential of laboratory sandbox experiments and studied in detail the impact of the injection near field on the larger scale transport process. Thereto we filled a sandbox with sediments, which were characterized for hydraulic conductivity prior to filling. The latter was then accomplished in such way that different source zone release conditions were arranged by modifying the hydraulic conductivity of injection near-field, while the surrounding hydraulic conductivity field remained unchanged. The experiments in this first sandbox model gave us confidence in laboratory sandbox models and showed that source zone release conditions are of importance for plume development. In detail, we found that source zone release conditions affect the first and second temporal moments, corresponding to the mean arrival time and the spreading of breakthrough curves and the spatial spreading of solute plumes in both the longitudinal and the transverse direction. We further found that in future experiments monitoring of the injection function and subsequent consideration of the measured injection function in the analysis of breakthrough curves might be beneficial for proper parameter estimation. 
In a second study we examined flow and transport in cube shaped sediment samples before and after freezing. Thereto we developed a cube shaped experimental setup, which allows for fill of sediment, performance of flow and transport experiments, freezing of the entire apparatus and withdrawal of a frozen sediment cube from the apparatus. This is an ongoing study. However, first results suggest that the apparatus works and there are only small changes in flow and transport parameters pre- and post- freezing. This is promising for the following experiments. In future studies the frozen sediment cubes will be utilized to arrange heterogeneous sediment formations in sandboxes. Thereto development of an apparatus is ongoing, which will allow to utilize the well explored frozen sediment cubes from experiments in the cube shaped experimental setup. Such experiments will allow experimental upscaling from the dm- to m-scale of the following processes: flow, conservative transport, reactive transport, reactive transport including feedbacks (precipitation and dissolving).
